Fine grained rock exhibits a non-visible or nearly non-visible crystalline structure on a fractured surface. On the opposite end, a coarse grained rock exhibits mineral crystals of the rock's constituents on a fractured surface. The larger the crystals, the coarser grained is the rock. Basalt would be an example of a fine grained rock. Granite would be an example of a coarse grained rock.
What is the difference between fine-grained and coarse-grained?
Fine grained has larger crystals and coarse grained has smaller crystals
What causes an igneous rock to have a fine grained or coarse grained texture?
The granularity of igneous rock depends on of the temperature of the magma and how rapidly it solidified. ...

Why are raindrop impressions are preserved in in fine grained sedimentary rock rather than a coarse grained?
because raindrops have small particles and coarse grained sedimentary rocks have big particles so it is easier for raindrop impressions to occur in fine grained sedimentary rocks ...
